In their simplest form a query may consist of one single word or a phrase. With the tips provided on this page you may extend your query to obtain better results. The tips will introduce you to the basics of the query language and will help to familiarize yourself with our Search engine.

• Search for words with the same prefix. If ou enter 'sub*' in the query form, the following words will be found amongst others: Submit, submarine, submerge etc.
• Search for all forms of a word. For example, if you enter 'sing**' in the form, the following words will be found: Sing, singing, sang, sung etc.
• To search for words occuring close to each other in the text, use the keyword NEAR instead of AND. With the queries 'System AND Security' or 'System NEAR Security' the words 'System' and 'Security' will be sought on the same page. By using NEAR the results will we sorted by the proximity of both words. The closer the occurance of both woords, the higher the ranking of the result page.
• Improve your queries by using the keywords AND NOT to exclude specific terms from the search. For example, if you want to find all occurences of 'surfing' but not the phrase 'internet surfing' then type in:
  'surfing AND NOT internet'
• Add the keyword OR to your query to find all occurences of either the first or the second term. Example:
  Bill OR Monica
  This query will find all pages, were either Bill or Monica or both are mentioned.
• Enclose your keywords in quotes to have the search terms processed literally by the search engine. Example:
  "System near security"
  Index server will search for the phrase 'system near security', near isn't interpreted as a keyword. If you enter the query without quotes:
  System near security
  Index server will search all documents for occurences of the words system and security.
